Assert for a non-null gfid failed in client_pre_getxattr_v2. From bt, it looks like a NULL gfid was passed to afr_shd_full.

Most probably it is because of the change in gf_link_inode_from_dirent() in your patch. Why did you make that change? Wondering if we need to change afr/ec code accordingly.

Please hold on. I'll let you know whether changes in afr/ec are necessary. I am thinking whether that change is really necessary.
